1. Match the division problems with their estimated quotients correctly.
Column A Column B
(a) 93 ÷ 27 (i) 5
(b) 903 ÷ 62 (ii) 3
(c) 573 ÷ 61 (iii) 10
(d) 305 ÷ 63 (iv) 15

WorD Problems
Example 1: A wholesaler has 11232 kg of wheat contained in 24 24 11232 468
sacks equally. Find the weight of wheat in each sack. – 96
Solution: Total quantity of wheat = 11232 kg – 163
144
Number of sacks = 24 192
Quantity of wheat in each sack = 11232 ÷ 24 = 468 kg – 192
0
Thus, the weight of wheat in each sack is 468 kg.
Example 2: There is an equal number of students in each of the 8 houses of a school.
If there are 488 students in the school, how many students are there in each house?
Solution: Number of houses = 8 8 488 61
Total number of students = 488 – 48
Number of students in each house = 488 ÷ 8 = 61 8
Thus, the number of students in each house is 61. – 8
0
